Ryzen 1700x precision boost??? nothing

Using Aida 64 for a stress test, and monitoring the cores on my 1700x with Ryzen master and or windows performance monitor, my CPU sits right at 3.4, never moves at 100 load. (says precision boost 3.8 on the box) I am using a Noctua U9S... I know its not the best cooler but it keeps my temps quite low.

Even at the start of the test with 100 percent usage, nothing happens when its cold or hot.

In my MSI x370 bios the settings for the boost is just "AUTO" or "DISABLE" it is on auto of course.

Am I missing something here?

More about ryzen 1700x precision boost
  1. Precision boost is similar to the older Turbo Boost in the FX series. It kicks in when certain criteria are met like only 2 cores loaded and only when there is enough cooling headroom for it.
    Reply to bgunner
  2. Yes my FX chip would kick in during all these tests with the same cooler... had no issues there. The precision boost won't do anything! Even during gaming.
    WHen i'm looking at Ryzen master, sometimes it will randomly jump up to 3.8 for like 1 second and come right back down randomly... this is quite strange. I tried gaming, and watching youtube all while monitoring ryzen master and it didn't budge at all...

    according to ryzen master, while running aida 64 at 100% load, my temps with the noctua U9S level out at 51.25 and the CPU stays at 3.5... ALWAYS. There HAS to be more head room at that temp under full load to clock up! Or it should clock up while its cooler right?

  3. OK, I think we are confusing what happens with the two different chips, FX vs. Ryzen. Ryzen is designed to only Boost 2 cores only when those cores are called apon. This means the other 14 cores are doing mostly nothing.

    Try loading just one core and see what happens. Try using Prime95 since you can select how many threads you want to test. I do not know if Aida 64 is able to do this or not this is why I suggest using Prime95.

    EDIT: please click on this link: And then scroll down until you see this header: SenseMi Stage 2: Precision Boost and it will explain more on how Precision Boost works.

  4. Ooooh it doesn't boost all the cores? okay thats probably whats happening then.
    I did notice something strange, after I turned off the aida64 stress test and it slowly brought down the load, it would go up to 3.8 for 1 second and ramp down and go up and down and up and down the entire time, but it was only for a second... kinda strange. You would think it would just ramp up. NONE of the cores ramp up when the test is on...
    I am monitoring the cores in Ryzen master, should I not see at least one or two cores go up to 3.8 while its cool?
    Reply to glytch5
  5. No, not if the load is spread across more than 2 cores. Since Aida loads all cores/threads it will not allow for the boost in speed. The program needs to load 1 or 2 cores only or it will run at its stock base speed. This is why I suggested for you to try Prime95 where you can tell it to load 1 - 16 cores/threads. This would allow you to see the precision boost actually work.

    The reason you are seeing the jump is frequency is because the load is now off all the cores and what the CPU is working on is either single or dual threaded so you see the jump in frequency.

  6. I see. Thank you! Is it strange that when playing a game multiplayer in windowed mode while watching Ryzen Master, I did not see any boost either? What exactly does that boost help with?
    Appreciate the heads up, i'm new to stress testing and stability/over clocking style things... and new to Ryzen of course.

    Many games take advantage of multi threading, this means that they use more than one core/thread. Now most games now use up to 4 cores/threads and soon will support even more. Because games use more than the 2 core /thread limit for precision boost the CPU sits at its base frequency.

    What would precision boost help with? It helps with "lightly threaded" applications/programs. This means that programs that use a single core/thread or two cores/threads will get the added frequency to help finish the task quicker. By finishing the cued process quicker it can go back into a energy saving state quicker making it more efficient. Now because of the allotted wattage envelope is still met because only 2 cores/threads are boosted it is still more efficient than boosting all cores/threads or none at all. for more on this read the article I linked before and do a google search for a much more in depth explanation of it.

    We all have a learning curve when trying to understand how components work to start with but as your knowledge grows the new tech wont seem to be such a steep curve. :)

  8. Thanks!
    This may sound dumb but, do you know of any applications or software I can run while monitoring in Ryzen master to watch the boost happen?

    I can see how this conversation would tie back to single threaded performance for in game, and why many people would seriously want to overclock these CPUS for games that use multi threaded... my FX chip was at 4ghz while gaming, now i'm using a clock at 3.4... even though the ryzen chip has better cache and newer architecture, i'm sure that is enough to override the slower clock speeds.

    You are the solution master on this one. I think I got lucky with ram, my sticks run at 3200 CL14 at stock voltage stable...

  9. For a program to load a single or more threads use Prime95. You can tell it to stress 1 core, 2 cores, 3 cores ect. because it allows you to select how many threads you want to stress.

    Prime95 is a free program and is good to help tell if your CPU is stable or not OR you can join groups and try to find the highest possible prime number, But that I doubt interests the majority of the uses of Prime95. When you open the program it will ask you what you want to do Join Gimps or just stress test? Select just stress test. Use the Blend test and for thread number set it to one. This will stress a single core/thread so you can watch and see what the boost option does.

    Here is the link to Prime95:

  10. I am currently doing what you said right now... I set the test the core to 1... nothing is happening. Temps are about 52 and the cores aren't moving up or down...
    I could never tell if prime95 was doing something or not.

    I do see the cores boost up when i'm closing programs or opening some... flashes up to 3.83 for about half a second... none of these stress tests seem to make the core want to boost.

  11. If you are using Win 8 or Win 10 open up task manager and select "performance". Left Click on the CPU readout on the left just to insure that you have proper graph up on the right. Now right click on graph on the right and select "Change Graph to" then left click on "logical Processors". This will give you a graph will 16 boxes one representing each core/thread. With prime 95 running one core should be fully loaded and able to be seen in the graph by the line being at the tip of the graph. While watching this you can also see if the frequency is being boosted on the bottom of task manager under the graph.

    It is possible that Ryzen Master is multi threaded and preventing the boost to kick in. Also turn off any other programs you are running in the background to try to prevent any conflicts with the boost working.
    Reply to bgunner
  12. Still nothing.... it boosts up to 3.7 for a split second and goes back down to 3.4 while only one thread is enabled on prime95 without ryzen master on. This is strange.

    I emailed AMD about this a few days back, they have not got back to me. I have never seen the clock boost up beyond 3.4 for more than about .5 to 1 second at a time.

    I could take a small video and upload it to my drive and post a link if you think that would tell you anything... my FX would just boost up and be happy.

    Another note... I have no over clocked this thing at all, however ryzen master says my CPU is 3.5ghz, and when I have MSI gaming app open it also says its 3500.... does that mean anything? in the bios its 3400.
    Reply to glytch5
  13. What does CPU-Z say for a frequency? Windows OS is notorious for saying the wrong speed so its reading wont help, Ryzen master is very new and may have a bug or two and only time will tell on this, I have never used the MSI gaming app so I personally can not speak of how well it works or how reliable it is But I have used CPU-Z for years and it is excellent at telling the CPU frequency and core voltage. If you do not have experience with this program you can click on the frequency read out and select the core you want to monitor. Either way you just want to load the CPU and it will tell you how high it gets. This should tell you if there is something wonky in the programs or not.

    It will take quite awhile before you hear back from AMD on anything because they have so much they have to do and support that it takes time to get through all the Email support tickets.

    WHen loading a single core, what does CPU-Z read for the frequency? Keep in mind that precision boost can adjust the core clock in 25 MHz increments. This means you may get a reading of 3,425 MHz, 3,450 MHz, 3,475 MHz ect. as it ups the core frequency.

    I don't remember if you mentioned it or not but are your BIOS for your motherboard currently up to date?
    Reply to bgunner
  14. CPU Z reads my core at 349.2. That is probably why the other programs show 3500.
    Same thing happens, the core jumps up into the 3.8 for a split second and goes back down.

    Also CPU-Z always reads my ram being slower than what the bios says which irritates me... it also does not show temps which I find annoying!

    So with your ryzen when you load the core, it smart boosts up and stays? My chip is probably bad, I am notorious for buying defective items in all different hobbies.

    My bios is not up to date... it is not the original either, its less than 2 months old. I have no yet flashed because things are working and I did not want to disrupt that, ya know what i'm saying?

    Also I wanted to add, when I stress the CPU in CPUZ and reference it against the same CPU, I get a better score, almost as if my CPU is lightly overclocked... strange right?
    Reply to glytch5
  15. CPU-Z shows the memory at its single data rate. Since ram is now DDR (Double Data Rate) you double the speed and get your actual speed. CPU-Z has never monitored Temps nor was it meant to. It is good for reading the core speeds, Actual Voltage, Memory speed (as long as you realize you need to multiply it by 2), telling what BIOS version the motherboard is currently running and more. It has it's uses but really not meant for every day use to monitor your system.

    OK, for your frequency issues, if the CPU frequency is reading 349X.2 AND your BIOS is set to run the CPU at 3400 as a base clock then your Precision Boost is working and there is another limiting factor keeping it from reaching its full potential. Most likely cooling preventing it going much higher. But before spending money on anything first double check the BIOS and make sure your CPU multiplier is set to 34. Base clock, which used to be called Hyper Transport for the Phenom's and FX CPU's and before that it was referred to as Front Side Bus, for the Ryzen motherboards is now 100 so 100 * 34 = 3400 MHz = 3.4 GHz. Many boards will not be quite dead on the 100 MHz but usually are within ±1 MHz so your actual frequency could read 3,434 MHz or maybe even 3,366 MHz. This last part is just extra information and not really important to your issue but good to know when it comes to understanding your frequency and how it gets to where it is.

    OK before you do Update, which I do recommend to do, make sure the new BIOS has the most recent AGESA update release in it. This will help with certain ram modules become compatible and allow for higher memory frequency's to be obtained. There is no need to update until they release A BIOS update with this in it. I can not remember the whole AGESA update number but I do remember it is 1.0.6XXXXX. It is also possible that the most recent update could help fix your Precision Boost issue. I do understand your position on "If It Is Not Broken, Don't Fix It." because some do get themselves in trouble doing so. Wait till the BIOS update has the latest AGESA update in it before updating your BIOS. Why flash right now and again in a month or so.

    There are a few factors that go into how your CPU rates against other CPU's of the same make and model. The motherboard, Memory Frequency, Core frequency, North Bridge frequency ect. The fact you can run your Memory at 3200 MHz which most others can not and add 100 MHz to your CPU frequency this would help in aiding your standing in the comparison.

  16. I think my ram works because I made sure to buy Samsung B dies, and also made sure to only buy sticks that were listed under pass for support for the motherboard... I spent a lot of money on them but it paid off.
    I went into my bios just now to check out the CPU frequency, and it is set to auto... however when I try to change it, it won't let me. Even if I set the explorer mode to expert instead of standard... I found this strange! I had no trouble setting it to whatever on my MSI FX boards. The only way I can change the frequency is by settings up game boost, it puts it at 3.9. Even then I can't play with it. Perhaps I should just flash.... I do not know about the aegis thing, I did not see that on there.

    I would think that even though i'm not using an enourmous cooler, the noctua U9s would allow for some temperature headroom over a stock cooler, it keeps the thermals down in the low 50s at full load or while gaming.

    Thanks for all the info. I did not see that hyper trasport. I also could not change the precision boost value. Its not really letting me change anything, when you click on it, or push enter or use arrows it does nothing. I was not expecting that. I will have to tinker and let you know what I find. That was a nice piece of info though man I really appreciate all the effort you are putting into me!

    AMD did get back to me, they said to try settings the power plan to the Ryzen specification or just changing it.
    Reply to glytch5
  17. There was a Patch for windows put out that added the Ryzen power plan to windows. The issue was that the OS was trying to control the CPU's power and frequency and it was causing issues with Ryzen CPU's. This new power plan gives the CPU the control of its power and frequency control. By now your OS should have already updated with this patch so try and see if your Power plans have one labeled as Ryzen. If you do not have it you can download it.
    Reply to bgunner
  18. Yeah I don't have that power plan...
    Reply to glytch5

    Download the 17.10 chipset driver and install. It is supposed to have the power plan in it.
    Reply to bgunner
  20. Yessir I got it going. No change yet. AMD also recommends that I reset my bios, or basically clear CMOS. Still no effect with the updated power plan. I'll let you know! Thanks man.
    Reply to glytch5
  21. Okay so I updated the bios... and did the power plan. Same thing. Not change. In fact now CPUZ reads my CPU frequency even higher at 3499
    -Just now as I minimized this window to read the clock, I watched it jump up to 3870, and then right back down, however in the single threaded stress test, I get no increase in clock, or decrease.
    Reply to glytch5
  22. your boost is working if you are getting readings as high as 3870 just for the short time that process needed to run. As for the reading of 3499 this could possibly be the first step in the Extended Frequency Range (XFR) due to the cooling.
    Reply to bgunner
  23. Hmmm... interesting! So you think the motherboard is saying "okay this guy is keeping his stuff fairly well cooled, i'll go ahead and crank up 100mhz" ?
    And then when I open a program is kinda goes "BOOM!" and then immediately simmers down when its done loading? I guess that makes sense but I really thought that precision boost would stay up. I'll have to chat with AMD some more.

    I wanted run this by you as well... with this third MSI board, my debug LED for iGPU is always on... I called MSI about this and the only thing he could think of was two things:
    1 being a faulty LED controller.
    2 being that since this particular CPU does not have integrated graphics, that light will always show. he though the bios update might fix it but it does not. Not keep in mind this is not the VGA LED, I tried moving the GPU around and trying a different one to make sure.
    Reply to glytch5
  24. I would speak with MSI more on this as the tech should find the answer for you on what it is supposed to do. He/She can talk to the higher level techs to get this answer. Do not settle with an unknown with this. Get a definite answer on what it is supposed to do, be on or off. Since I do not have that board I can not say from experience what it is supposed to do.
    Reply to bgunner
  25. I wanted to come back to this...
    I went to a local computer store, and they had a machine set up with a the same CPU as mine, only it was on an ASUS board instead of an MSI board.
    Their chip is showing Precision boost all over the place just while surfing the web... mine won't do that! I know it is turned on in the bios... what is going on here?
    I am starting to think my chip is not working.
    Reply to glytch5
  26. without reading the whole thread again I want to ask, have you tried to to do an RMA on the motherboard?
    Reply to bgunner
  27. This is the third out of three motherboards that work. So yes, but not this one.
    Everything else is finally working, but I cannot figure out a way to get the P boost to actually happen visibly. Stressing it with bench marking software does nothing. Occasionally I will see it bump up for a split second for no apparent reason but its rare.

    I did not test this on the other motherboards because one was a brick and the other I hadn't got nearly this far.
    The only thing different the guy had at the shop was a asus prime mobo, and a hyper 212 evo on there. I have a noctua u9s... so I guess my thermals could be slightly higher but I doubt it...
    I REALLY want proof this things works... so far I cannot find it.

  28. I wanted to add, all I had open on windows 10 with the floor model ryzen 1700x was ryzen master and firefox opened with like newegg or something on the page... the core constantly boosted up to 3.9 and back down.. .just while doing that.

    I currently have 10 windows open plus other programs and am constantly clicking vigorously all over the different tabs... it ant doing a damn thing! lol
    Reply to glytch5
  29. At this point it is best to get in touch with MSI's support and AMD support together to figure out which piece is causing the issue.

    If I'm not mistaken, didn't one of them suggest clearing the Cmos / resetting the BIOS? Did you actually do this by either moving the jumper or removing the Cmos battery?
    Reply to bgunner
  30. I did not do that yet... but I tried setting everything back to stock.
    I don't see why that would help... I do have a ton of jumpers sitting around.
    AMD pretty much is no longer responding and since it is the weekend I can't call MSI.

    On the subject of MSI. They have released a new bios with a new AGESA code... should I bother getting that? I would think since my memory works how I want it to there is no reason.
    Reply to glytch5
  31. This is up to you BUT MSI support will ask you to update your BIOS. So at this point you might as well be one step ahead in the trouble shooting.

    The jumper is already on your board, you do not need another. Without knowing the exact model motherboard (I know it is an MSI x370 but they made many different models) I can not tell you exactly where it is located. So to make things easier, unplug your power supply from the wall and remove the button battery on the motherboard for 30-45 seconds and replace. This will wipe your BIOS and force the motherboard to scan all the hardware that is installed. Yes this can make a difference and is different than just setting the BIOS to factory settings.
    Reply to bgunner
  32. The jumper isn't on the board... I tried it. No effect. damn I was hoping that would work.
    its a pro carbon x370
    Reply to glytch5
  33. SO just to be sure... when testing this with prime95 you want to go to the top and do torture test, set to blend test and set the threads/cores to 1 correct? That has zero effect on the speed... neither does aida64.
    Reply to glytch5
  34. It is odd that your board has only 2 pins for clearing the Cmos. For future reference a flat head screw driver will work also as you just need to connect the two pins for a short time. When you tried this did you make sure the power supply was unplugged from the wall? Because if it is not then it will keep the settings.

    Yes a torture test, blend is good and set it to run on 1 thread/core this should force it to boost the core speed.
    Reply to bgunner
  35. I did not unplug the PSU but it completely reset all the settings that were on there so I know it indeed worked. I had to re do my XMP and everything.
    I've tried clocking my ram back down, turning off virtualization. Messing with power state stuff. Pretty much everything I can think of in those bios that would effect such a thing.
    This really bites... I so don't want to have to use my warranty on this CPU. I'll be without my main computer for a month and a half. It is starting to look like that is my option here.
    Reply to glytch5
  36. aaah... I think im ganna have to go down to my little computer shop and beg them to let me put my 1700x in their mobo and see if it does the same thing... that will tell me at least if its my motherboard or my chip... I doubt they will let me do that though.
    Reply to glytch5
  37. AMDs tech support is so annoying. I told them everything I said here, about the stress testing... about the other CPU I tried at the local computer store that worked and how mine is not... and how I cannot seem to get my chip to boost ever. They say:

    "With this technology Ryzen CPUs will fine tune processor performance adjusted in real time to meet the performance demands of your game or app. So if there is a demand for more power, CPU will adjust the clocks to maximum frequency depending on the cooler and application demand.

    If you like to have the CPU running at max frequency all the time, you will have to adjust the Clock and voltage manually."

    dude COME ON!... I know man... they obviously did not read my mesage.

  38. I think im ganna just give up on this... about to just overclock to 3.8 and turn P boost off this is STUPID!

  39. I would have done that just to start with. lol But then again when I bought my FX 6120 and then again with the FX 8350 they never ran at stock settings from the get go.

  40. interesting... I have a corsair h100i V2, i'm hoping that will be enough for the bit of extra voltage I will need to run it at higher speeds. Thanks for trying to help me though man, that was nice of ya.
    Reply to glytch5
  41. That cooler will handle around 220W - 250W of heat generated by a CPU. It will definitely be enough to cool that CPU with a good overclock and the added voltage. Just remember that the Ryzen chips usually top out around 4 GHz so while overclocking watch the temps and voltage. If I am not mistaken AMD recommended not going over 1.35V (please double check this as for I could be stating the wrong voltage) for 24/7 use or it could hurt the longevity of the chip.
    Reply to bgunner
  42. I would hope its over 1.35 because that is what it is set at out of the box! Excellent news though... I would be happy with 3.8.
    Reply to glytch5
  43. Many times they set the voltage higher than it needs to be to allow for the weakest of all the CPUs. As an example my Phenom II 965 default setting was 1.38v but ran stable at 1.25v. So it is likely that your chip will run on less voltage than what the default setting is.
    Reply to bgunner
  44. So I spoke with AMD some more about this, they had me send them a picture of a benchmark running with Ryzen Master opened. They confirmed there is definitely an issue. They said I need to try a different motherboard to know for sure with the chip, and gave me the information for RMA.

    I am going to beg my local store to let me put my chip in their display RYzen system and check it... so looks like I got lucky again!
    If its the motherboard i'm going to very angry... that would mean 3 dud boards in a row. It is most likely the chip I am thinking.

  45. So here is what I discovered:
    I got to try three different Ryzen systems over the past couple weeks.

    So the first Ryzen I tried at the store was no longer there, the system had sold so I could not put my chip in THAT motherboard, however I got to test my 1700x on a different system, with the same motherboard.

    SO the original system worked perfectly, while mine did not. My system does not boost at all. The computer at the store would boost correctly.

    I went and visited with a tech, and he had a ryzen 1700 (non x variant)
    His 1700 was acting exactly like mine is... no boost no nothing with benching software, or other tasks. In fact his chip would boost DOWN at times.
    So for the hell of it we threw my CPU into that chipset.

    My chip would boost SOMETIMES... but mostly not at all!

    So I have tried three different chips on two different motherboards... one would boost properly, one would boost SOMETIMES, and the last would not boost up... but down instead... all tests were done on the same ASUS motherboard....

    Reply to glytch5
  46. I want to make sure I understand correctly what your chip did after trying it in a different motherboard at your local shop, Your chip did not boost at all? Correct?
    Reply to bgunner
  47. It boosted randomly a tiny bit... for about .5 seconds and it was totally random... like he would open edge after a restart, and the first open it would boost for a split second, if we closed edge and re opened it, no boost. We could not "make it" boost... and this was at a tech station. His 1700 non X would not boost either... same exact thing.
    the 1700x they had there that is now sold WAS boosting properly... weird right?

    The tech said "your computer may not NEED the boost" he was saying he built a machine with the older FX 9350 or whatever, him and the customer never got that machine to boost... that was the chip that had the HUGE turbo boost. I know thats a whole different scenario but, that is kinda what he was driving at... very weird right?

    so I have tried three different ryzens, two while standing with a full time tech and we could not get a boost... idk why that one machine that was on display was boosting... perhaps it had all kinds of bloatware runnin
